BATTING.

i Application led August 11, 1921. Serial No. l191,639.`

To all whom t may concern `Be it known that I, ALFRED C. BROWN, acitizen of the United States, and a resident of Lockland, in the countyof Hamilton and State of Ohio, have invented certain new and `usefulImprovements inBatting, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification.` a

My invention relates to cotton batting such as is employed for variouspurposes as for example upholstery, comforts, cushions, and the like.Suuch batting is made up into webs, and the webs rolled into circularrolls for shipment, and later unrolled for use.

4The manufacturev of cotton batting involves in its essentials a seriesof carding machinesl from which the combed fibre comes out and fallsonto a travelingbelt, said belt accumulating the fibre webs dropped fromthe various machines and matting them together into a thick web which isrolled up or folded up` asdesired. The action of the fibres falling fromthe carding machine on a traveling table or belt `forms the webs, andthere are several customary ways of depositing the fibre on the table orbelt.

When the various superimposed webs are matted into a fairly homogeneousthicker web, and this web is formed into a roll, it is quite difficultto unroll it again into the same shape as it was prior to rolling, sincethe fibres are but loosely held together and the surfaces rolled againsteach other tend to adhere.

This fact necessitates the use of strips of paper laidover the thick webas it is rolled into a cylindrical roll, which adds considerablyl to thecost of the bale or roll, and is a great nuisance to the user. The paperstrips accumulate on the floor and table where the batting is used andmust be cleared away.

Even with the strips of paper used as a separating agent the fluffysurface of an uncalendered web tears easily in handling.

It has been the practice in some instances to form up a thick web ofbatting, as above described, and then calender the whole web, but thisis unsatisfactory as the elasticity of the batting is largely reduced,and a number of layers of calendered batting must be used where onewould sufiice to get the neces' sary thickness.

It is the object of my invention `to do away with 'the necessity ofcalendering the webs of batting, and with the use of paper, and toproduce a batting web which is easily rolled and unrolled and easilyformed into folds for use in upholstery.

This I accomplish by that certain form of batting and process of makingthe same to be hereinafter more specifically pointed out and claimed.

In the drawings,

Figure l is a diagrammatic view showing one method of making cottonbatting, together with the appliance necessary in forming my novel formof batting.

Figure 2 is a like view showing the camel back or run out method ofmaking cotton batting together with my appliance in connectiontherewith.

Referring first to Figure 1 it will be noted that the outlets of aseries of carding machines are shown at 1, and of another series in linewith the first series are shown at 2. The traveling beltJ oraccumulating table is shown at 3, and the matting rolls for lightlyformingthe various 4webs into a full thickness web are shown at 4.

I have located between the first 'and second series of carding outlets aset of calendering rolls 5, which lie just above the travcling table andreceive the webs from the first set of carding machines and calenderthem in the usual manner.

The calendered web drops right back to the table and has superimposed onit the webs from the remaining carding machines, after which the wholeis formed into a single web by the matting rolls and is ready for beingfolded, rolled or baled.

It will be noted that the calendered surface of the complete web willserve as a complete, non-adherent liner for a roll of batting as at 6and that this will prevent the adherence Vof fluffy cotton in unrollingor unfolding.

Furthermore, there being but one third of the cot-ton, in theparticularV instance shown, which is calendered, the resilience orelasticity of the completed web is not materially affected.

If the cotton is to be permanently doubled or otherwise folded after itpasses the matting rolls, then but a portion of the first series of websis calendered, the remaining portion of the said webs being allowed totravel along with the portion that is calendered, but not subjected topressure due to the short length of the calender' rolls. This remainingportion that is left uncalendered is the part that is folded overleaving-a calendered bottom to the web.

In case the webs formed as above are to be formed into upholstery folds,then the rolls may be so arranged that the outer surface of the fold isof calendered inaterial, the folds on the inside of the completed fold 7beiney entirely free from calendering. i

The essence of the invention will be evident from the foregoingdescription in which no attempt has been made to illustrate the actualmachine, The webs from the carding machines, in' forming an ordinarybat,' run from eight to sixteen, depending on the weight and thicknessdesired. A single web from one cardinp machine would ordinarily be toolight and thin to calender properly, so as illustrated in diagramiii-Figure I. I take for ei:- amplc three of these webs. If thecompleted bat is tobe folded longitudinally. then the calendered portionis only of the width of the ultimate fold.

In 'the run out type of machine the web at 7 is deposited on Athetraveling` table ahead of the calendering rolls and the webs 8, 8,deposited after the calenderingrolls.y the result beingv the same asbefore.v In its essential respects my novel form of batting` is notconcerned with the width or uniformity of thecalendered portion of thebats, but with the fact that I form as an a. series of superimposedlayers of deposited fibre matted to form the bat, with a portion of someofthe layers of the bat calendered prior to the matting' to form anon-adherent contiguous surface for the bat when formed into a package.n

2. A bat of cotton or the like, comprising a series of superimposedlayers ofdeposited fibre matted to form the bat1r with a plurality ofthe bottom layers calendered, at least -in part. prior to the mattingofall the superimposed layers` whereby a non-adherent contiguous surfaceis provided for the hat when formed into a package.

3. A bat of cotton or the like, comprising;`

a series of superimposed layers of deposited libre matted to form thebat, with a pluralit)v of the bottom layers calendered for the entirewidth prior to the matting of all the superimposed` layers, whereby anonadherent contiguous surface is provided for the bat when formed intoafpackage.
